About the "topfind"?

Question

When I input #use "topfind" ;; in top-level manually, it works as below:

 #use "topfind" ;;
 - : unit = ()
 Findlib has been successfully loaded. Additional directives:
 #require "package";;      to load a package
 #list;;                   to list the available packages
 #camlp4o;;                to load camlp4 (standard syntax)
 #camlp4r;;                to load camlp4 (revised syntax)
 #predicates "p,q,...";;   to set these predicates
 Topfind.reset();;         to force that packages will be reloaded
 #thread;;                 to enable threads #use "topfind" ;;
  - : unit = ()

However, when I put #use "topfind";; in ~/.ocamlinit file, it doesn't work:

>cat ~/.ocamlinit
#use "topfind";;
#require "str";; 
(* #use "money.ml" ;; *)

>ocaml
    Objective Caml version 3.12.0
# #list ;;
Unknown directive `list'.

It seems a strange question, isn't it?

Answer 1

Obviously ocaml doesn't load that .ocamlinit. Put some print_endline in it to verify. Some ideas:

• You can use -init option to specify ocamlinit file explicitely.
• Maybe ocaml is some (wrong) alias in your shell?
• Try strace -f -ttT -e open $(which ocaml) to see where it looks for ocamlinit.

ygrek

thanks for your quick answer.

You can use -init option to specify ocamlinit file explicitely.

%ocaml -init ~/.ocamlinit works

Maybe ocaml is some (wrong) alias in your shell?

no ocaml alias

Try strace -f -ttT -e open $(which ocaml) to see where it looks for ocamlinit

%strace -f -ttT -e open $(which ocaml)

#

The reason is that there is a .ocamlinit file in the current directory. so ocaml uses it instead of ~/.ocamlinit.

thanks!
